AC_REPLACE_FUNCS([getaddrinfo]) in 8.1.3

AC_REPLACE_FUNCS([getaddrinfo]) won't correctly detect getaddrinfo on
Tru64 UNIX because the function doesn't exist under that name in libc.
>From <netdb.h>:
#if defined (_SOCKADDR_LEN) || defined (_XOPEN_SOURCE_EXTENDED)
#define getaddrinfo ngetaddrinfo
#else
#define getaddrinfo ogetaddrinfo
#endif

The original code in 8.1.1 was:
AC_MSG_CHECKING([for getaddrinfo by including <netdb.h>])
AC_TRY_LINK([#include <sys/types.h>
#include <sys/socket.h>
#include <netdb.h>],
[getaddrinfo(NULL, NULL, NULL, NULL);],
[AC_MSG_RESULT([yes])
AC_DEFINE(HAVE_GETADDRINFO, 1,
[Define to 1 if you have the `getaddrinfo' function.])],
[AC_MSG_RESULT([no])
AC_LIBOBJ(getaddrinfo)])

So, what's the best way to merge the two? If getaddrinfo() is borked
on Windows, how about AC_TRY_RUN to test it out?
